Ancestors: ToolBuilder-Morphic-mt.251

Fix a regression in ListMultipleChooser that led to missing invalidations of the PluggableListMorphOfMany. Probably introduced by the recent refactoring of list morphs.

To reproduce, run the following snippet and select multiple items (but don't move the cursor after clicking):

        Project uiManager chooseMultipleFrom: #(foo bar)

Only the first selection event triggered a #change before.
